# Start Django ✨
[Django Documentation Tutorial](https://docs.djangoproject.com/ko/3.2/intro/)을 따라가며 코드 및 배운 내용을 기록합니다.
-
+- **기간** : 2021.08.23 ~ 2021.08.27
+- **목적** : Django 프레임 워크 기본 기능 익히기
+- **순서**
+ 1. Django 공식 문서를 참고하여 실습 진행
+ 2. 배운 내용 문서로 정리
+ 3. 매일 아침 8:40 스크럼 회의
+ 4. 피드백 반영하여 코드 및 문서 수정
## Django
> Django makes it easier to build better Web apps more quickly and with less code.

+# 02. Database and Admin
+
+데이터 베이스 설치 및 관리자 사이트 생성
+
+## 데이터베이스 설치
+
+- django는 기본적으로 SQLite : `mysite/settings.py`
+ ```python
+ DATABASES = {
+ 'default': {
+ 'ENGINE': 'django.db.backends.sqlite3',
+ 'NAME': BASE_DIR / 'db.sqlite3',
+ }
+ }
+ ```
+- 다른 데이터베이스 사용 시 [공식 문서](https://docs.djangoproject.com/ko/3.2/ref/settings/#std:setting-DATABASES) 참고
+ ```python
+ DATABASES = {
+ 'default': {
+ 'ENGINE': 'django.db.backends.postgresql',
+ 'NAME': 'mydatabase',
+ 'USER': 'mydatabaseuser',
+ 'PASSWORD': 'mypassword',
+ 'HOST': '127.0.0.1',
+ 'PORT': '5432',
+ }
+ }
+ ```
+
+- `TIME_ZONE` 설정
+ ```python
+ TIME_ZONE = 'Asia/Seoul'
+ ```
+
+<br>
+
+- `INSTALLED_APPS` 확인
+ ```python
+ INSTALLED_APPS = [
+ 'django.contrib.admin', # 관리용 사이트
+ 'django.contrib.auth', # 인증 시스템
+ 'django.contrib.contenttypes', # 컨텐츠 타입을 위한 프레임워크
+ 'django.contrib.sessions', # 세션 프레임워크
+ 'django.contrib.messages', # 메세징 프레임워크
+ 'django.contrib.staticfiles', # 정적 파일을 관리하는 프레임워크
+ ]
+ ```
+
+- 데이터베이스 설치 (`INSTALLED_APPS`에 대해서만)
+ ```bash
+ $ python manage.py migrate
+ ```
+
+<br>
+
+## 모델 만들기
+
+- **모델** : 부가적인 메타데이터를 가진 데이터베이스의 구조 (layout)
+- 우리의 `polls`앱에서는 `Question` 과 `Choice`라는 두 가지 모델을 생성할 것.
+
+<br>
+
+- `polls/models.py`
+ ```python
+ from django.db import models
+
+
+ class Question(models.Model):
+ question_text = models.CharField(max_length=200)
+ pub_date = models.DateTimeField('date Published')
+
+ class Choice(models.Model):
+ question = models.ForeignKey(Question, on_delete=models.CASCADE)
+ choice_text = models.CharField(max_length=200)
+ votes = models.IntegerField(default=0)
+ ```
+
+- 각 데이터베이스 필드를 `Field` 클래스의 인스턴스로 표현
+- `ForeignKey()` : 외래키 참조
+
+<br>
+
+- `INSTALLED_APPS`에 `polls.apps.PollsConfig` 추가
+```bash
+$ python manage.py makemigrations polls
+Migrations for 'polls':
+ polls\migrations\0001_initial.py
+ - Create model Question
+ - Create model Choice
+```
+
+- `polls/migrations/0001_initial.py` 파일 생성 확인
+- SQL 명령어 확인
+ - app 이름과 모델명을 이용해 테이블 이름 자동 생성됨.
+ - 필드명, 필드 타입 관례에 따라 자동 생성
+```bash
+$ python manage.py sqlmigrate polls 0001
+BEGIN;
+--
+-- Create model Question
+--
+CREATE TABLE "polls_question" (
+ "id" integer NOT NULL PRIMARY KEY AUTOINCREMENT,
+ "question_text" varchar(200) NOT NULL,
+ "pub_date" datetime NOT NULL);
+--
+-- Create model Choice
+--
+CREATE TABLE "polls_choice" (
+ "id" integer NOT NULL PRIMARY KEY AUTOINCREMENT,
+ "choice_text" varchar(200) NOT NULL,
+ "votes" integer NOT NULL,
+ "question_id" bigint NOT NULL REFERENCES
+ "polls_question" ("id") DEFERRABLE INITIALLY DEFERRED);
+CREATE INDEX "polls_choice_question_id_c5b4b260" ON "polls_choice" ("question_id");
+COMMIT;
+```
+
+- 데이터베이스 모델 관련 테이블 생성하기 (변경사항 데이터베이스에 적용)
+```bash
+$ python manage.py migrate
+Operations to perform:
+ Apply all migrations: admin, auth, contenttypes, polls, sessions
+Running migrations:
+ Applying polls.0001_initial... OK
+```
+

+Out[8]: datetime.datetime(2021, 8, 24, 17, 49, 58, 504533)

+
+# Question
+def __str__(self):
+ return self.question_text
+
+# Choice
